Abstract: Device containing a vacuum chamber 30 and situated therein a substrate 10 and a vaporisation crucible 22 filled with inorganic materials 24. Situated in the region of the vacuum chamber 30 is an electron beam or laser gun 26, the electron or laser beam 27 of which is directed at the crucible 22. The device is employed for coating a substrate surface 18 e.g. a plastic film with a thin coating of inorganic materials, such as e.g. silicon oxides, by vapour deposition of the inorganic materials 24.   The electron or laser beam 27 of the electron beam or laser gun 26 is directed at the surface of the inorganic materials 24 in the vaporising crucible 22. The electron or laser beam 27 forms an angle .alpha. of 10 to 80° to the surface of the inorganic materials 24. On vaporising the inorganic materials 24 an overhang 25 is formed in the inorganic materials 24 and, geometrically, there is no line of sight between the vaporising inorganic materials and the substrate surface 18.   The process performed in the device leads to substrates e.g. plastic films the surfaces of which exhibit no inhomogenieties such as sprayed material, particles or droplets of inorganic materials.

Abstract: Ce procédé de nitruration permet de former une couche de nitrure relativement épaisse sur une surface d'aluminium contenant du silicium. On décrit aussi un adjuvant de nitruration comprenant comme ingrédient principal de l'aluminium contenant un métal pouvant se lier solidement à l'oxygène, tel que le lithium ou le bore, et qui, lorsqu'il est en présence de silicium, ne forme pratiquement pas de siliciure, ainsi qu'un adjuvant de nitruration comprenant comme ingrédient principal un alliage aluminium-magnésium-cuivre ou magnésium-zinc-cuivre mis en contact avec de l'aluminium, lors d'un traitement thermique effectué en présence d'azote. Ceci permet de former facilement une couche épaisse de nitrure, également à la surface de l'alliage d'aluminium contenant du silicium. Ce procédé convient particulièrement pour nitrurer la surface d'un alliage aluminium-silicium qui présente une excellente coulabilité.

Granted: 2008-01-08
Abstract: In a flexible endoscope having a flexible insertion tube comprising a tubular, biocompatible elastomeric outer covering thereabout which encloses an interior space, the improvement according to the present invention comprises a vapor barrier between the outer covering and the interior space. Thus, vapor, such as hydrogen peroxide or other sterilants, passing through the outer covering from an atmosphere thereabout is prevented from entering the interior space by the vapor barrier. Further, the vapor is thus prevented from interacting with substances, such as lubricants, within the interior space to produce agents harmful to the elastomeric covering.

Title: Apparatus and method for inerting and venting the containment atmosphere in a nuclear power station
Inventor: ECKARDT BERND
IPC: G21D1/02
Filed: 1996-09-02
Granted: 2007-05-08
Abstract: When hydrogen is generated within the containment (8) of a nuclear power station, its containment atmosphere (CA) must be inerted. In order to avoid a pressure buildup within the containment (8) when inerting of this type is carried out, an apparatus and a method are specified which make it possible to bleed (vent) the containment atmosphere (CA) simultaneously.  For this purpose, according to the invention, a reversible activity holdup device (4, 4') is provided, which makes it possible to vent the containment atmosphere (CA), without radioactive material being released into the surroundings. It is thereby also possible for the containment (8) of a nuclear power station to be inerted even prophylactically, so that the safety of the nuclear power station plant is markedly increased.

Abstract: Disclosed are expressible reverse gene constructs, and oligonucleotides, whi ch are characterized by the ability to hybridize with an Ii mRNA molecule, thereby inhibiting translation of the Ii mRNA molecule. These compositions are referred to generally as inhibitors of Ii expression. Also disclosed are MHC class II-positive antigen presenting cells containing an inhibitor of Ii expression. A particularly important class of MHC class II-positive antigen presenting cells are malignant MHC class II-positive antigen presenting cells (e.g., leukemia, lymphoma and melanoma). Also disclosed are methods which result in the displ ay of an autodeterminant peptide, in association with an MHC class II protein, on the surface of an MHC class II-positive antigen presenting cell. In such methods, a specific inhibitor of Ii synthesis is introduced into an MHC class II-positive antigen presenting cel l. The specific inhibitor functions, directly or indirectly, through the formation of a duplex molecule with mRNA encoding Ii. The formation of t he duplex molecule functions to inhibit Ii synthesis at the translational level. Also disclosed are therapeutic methods for the treatmen t of malignancy in an MHC class II-positive antigen presenting cell, and autodeterminant peptides which are isolated from an MHC classII- positive antigen presenting cell.
